MIT Research Positions in Machine Learning for Health

MIT Postdoctoral Position in Machine Learning for Health

The Massachusetts Institute of Technology (MIT), Institute for Medical Engineering & Science (IMES) invites applications for a Postdoctoral Associate position in Machine Learning for Health. This is an immediate opening for a highly motivated researcher interested in developing machine learning methods for latent representation learning and generative modeling from complex, multimodal, time-varying clinical data, with the goal of informing sequential treatment decision-making and generating actionable insights with high potential impact in clinical medicine.

The project offers opportunities to develop and apply novel machine learning and statistical approaches to generate clinically meaningful insights from observational health data, including clinical time series and physiological signals, with extensions to multimodal learning from medical imaging and physiological waveforms. The successful candidate will join a multidisciplinary team working at the interface of computational methods and clinical medicine to develop approaches with high translational value that inform patient care and treatment decisions.

• Ph.D. in Computer Science, Machine Learning, Statistics, or a related field
• Strong publication record in top-tier machine learning and AI venues
• Demonstrated ability to conduct independent, high-quality research

• Probabilistic and generative modeling, including latent variable models, deep generative models, and scalable inference methods, with an emphasis on structured and stable inference (e.g., constrained variational inference [1]).
• Representation learning from time-varying data [2,3,4], including interpretable structure discovery and latent state representation learning for forecasting and sequential decision-making.
• Dynamic systems and state-space modeling, including deep dynamical systems, switching state-space models [2,3,4].
• Incorporation of inductive biases, structural constraints, or domain knowledge to improve robustness, generalization for robust learning. Leveraging mechanistic models or domain knowledge to guide inference and gain mechanistic insights.
• Expertise in the following advantageous but not required: Multimodal representation learning, causal inference, and robust modeling under distributional shifts
• Publications in NeurIPS, ICML, ICLR, AISTATS, UAI, AAAI, MLHC, ML4H, CHIL or equivalent strongly preferred

Applicants should send a CV and a brief description of research interests, and expected timeline for starting the position to Li-wei Lehman (lilehman@mit.edu). Please specify your current affiliation and list 2–3 representative publications and venues. Applications will be reviewed periodically, and candidates whose background and expertise are a strong fit will be contacted for next steps.

Duties include conducting original research, publishing in top-tier machine learning conferences and scientific journals, mentoring students, and contributing to research grant proposal writing. This position is budgeted at an annual salary range of $71K–$74K.
